DEMOUNTABLE RIM FOR AUTOMOBILES.

Specification ot Letters Patent.

yPatented Mar. 13, 1917.

Application led December 29, 1915. y Serial No. 69,233.

To all Q/:wm it may concern y Be itV known that I, JL's'rLN S. HEnExwAY,

a citizenI of the- United States,`residing at River Falls, in the county of Pierce and State of lViscons-in, have invented a new and useful Demountable `Rim for Automobiles, ofwhich the following is a specilie tion.

The device forming the subject matter of this application is a wheel rim, adapted to be employed in connection with a pnemnatic tire.

The invention aims to provide novel meanswhereby the rim may be collapsed and Ievpa'nded.

Specifically, itis one of the objects o'f` the invent-ion to provide a removable 'rim section of novel form, adapted to be interlocked by novel means with the body portion ofthe rim to prevent relative movement between the body of the rim and the due to circllmferential strains.

Another object of the invention is to improve the latch mechanism which, being carried by the body of the rim, constitutes a means for holding the detachable section of the rim in place- It is within the province of the .lisclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combin-.rtion and arrangement of parts and in the details of construction Ahereinafter described and *claimeth it being understood that changes in the preciseembodiment of the invention herein disclos dcan be made with'- in the scope of what isJ-laimed, without departing from, the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a wheel rim constructed in accordance with the pres ent. invention; Y

Fig. 2 is a top pla-n of the rim;

Fig. '5 is a transverse section on the line 3f?) of ["ig. l, parts being omitted;

Fig. 1 is a plan of the. removable rim section; y

Fig. 5 is a longitudinal sectimi taken approximately' on the line 5-5 of Fig. 2;

Fig. (i is an enlarged elevation showing one of the abutments. y

The device forming the subject matter of this application preferably but not neces section,

` .apivot element 12 on which ls mounted sarily is fashioned from metal throughout and includes a rim comprisimg7 a resilient body 1 and a removable section The ends 3 and el of the body 1 are beveled. as shown at :5, and the ends li and 7 of the removable section 2 are inclined as shown at -8 to cooperate with the beveled ends 5 of the body, the construction being such that't-he section 2 may be removed inwardly, but cannot be removed outwardly.

In the ends 3 and 1 of the body 1 are formedvreeesses 9 havingr reduced mouths. Secured to the under face of the end l. and extended across one of the recesses 9 is a strap 10 hield in place by securing elements 11. Owing to the fact that the recess above alluded to is partially brideed across by the stl'ap 10, the said recess may b e described as being formed in the outer face of the end 4. i

Mounted in the end 3 of the bodyl is to swing a latch 14 cooperating with the under face of the end 3. 'lhe latch 14 is ytapered to define a resilient stem. 15 and a head 1U. rhein as shown in Fig. 5l, the latch 14 stands transversely of the rim, the head 16 of the latch is locatedto one side of the adjacent' recess tl. but when tln` latch extends longitudinally olf the rim, then`thehcad 1G underlies the said recess. The resilient Stem 15 of thi,l latch 14 and the end 3 are provided 4with interlocking elements where-....-

by the latch may be held longtlulinally,of

the rim, as indicated in dotted lilies in Fig.

3, these interlocking elements embodving a recess 1S formed in the end il and a boss 17 on the .stem 15 adapted to -be received in the recess.

rl`he,removable section 2 is providedV at its ends with extensions l5) shaped to lit within Jthe recesses 9. the extensions heimr reduced at 20. adjacent the ends of the section. ()b-` viously, the construction above described is such that when the extensionsl l!) are received. in the recesses t). the removable section 2` will be interlocked with'the body l against becoming detached by circumferential strains.

Mounted on the removable section'Q near to the end 6 thereof is an abutment 21 which maybe held in place b y securing elements 22.' An .abutment 23 is secured to the inner face .of the body 1, nearer to the end 3 of the body than to the end l' thereof. .The invention includes a lever 24 'bent upon itself adjacent one end to form an extension 25 defining n finger 27 und e sent 2G. Copernting with the lever 24 und the abutinents 23 and 2l in a manner to be described hereinafter, is si thrustbar 28.

1n prncticul operation, one extension 19 on the rei'iovuble section 2 is placed in the correspoiuling recess S) ot the body l above the strap '10. '.l.`he other extension 19 s'then forced upwardly through the corresponding recess J in the end Si; rlhereu'fter, the latch 1l is sunngnrouud from the solid line position oi Fig. 3 to the dotted line position thereofunder which circumstances the head 15 of thel latch will extend beneath the adjacent extension lJ und ninintnin the section 2 iu plut-e, the boss 17 on the 'latch in terloclling with the recess 18 in the end of the body l of the rim.

Should occasion require, recourse muy be hud'lto the lever 24 and the thrust bar 28 for the purpose of mounting the removable section 2 in place. Under such eircums stzuices7 the linger 27 of the lever 24 is engaged with the abutment 23, one end of the thrust bnr 2S being engaged with the abutment 21, and the 4other end of the thrust bar being engaged withr the seat 26 in the lever 24. By means of the lever 24 and the thrust bur 28, the left'lia'nd end of the re- ,.rnovuble section 2 '.(Fig. l) lmayfb'e pushed outwardly to place. As shown at 50, the ubutments 21 und 23 are undercut at their ends to retain a hold, respectively on the thrust hanf 28 and the finger 27 of the lever 24.

Having thus described the invention, what is claimed isz- A, wheel rim comprising a bodynnd a relatively short section removable as an entity from the body, the body and both ends of the section being provided with detachA ably internmggdelements which limit the outward movement of the section, the body and the section being provided with detachably interengaging elements which prevent relative circumferential movement between the section and the body; und members carried by the body and concting with the Seeond specified interengnging elements of the section to prevent inward movement of the ends of the section, one of said members bel ing movable to permit inward movement of the corresponding end of the section.

In testimony that .l claim the foregoing as my own, I have hereto affixed my signa- A ture in the presence of two witnesses.
